Tandem is a pure-player publishing house designed for children to 3-6 years. We created a reading mode adapted to their needs thanks to the “dual narration » of the stories. We mix classic reading with interactives packages and littles games during the storytelling thanks to the movement portrait/ paysage of the tablet. We want collaborate with authors and illustrators for extending the younger litterature which is in lack of quality devices. This collaborations is a good opportunity for the actors of this kind of literature to get more close to their customers.
